Answer:
We have 379.20grams of zinc present.
Explanation: The SI base unit for amount of substance is the mole. 1 moles is equal to one moles zinc, or 65.38 grams.
We can relate the number of moles of zinc to the molar mass of zinc.
Since 1 mole of zinc = 65.38g/mol
Number of moles of zinc = mass of zinc/ molar mass of zinc
From the question, number of moles of Zinc is given as 5.8moles We can calculate the mass of zinc present in 5.8 moles as
5.8moles = mass of zinc/ 65.38gmol-1
When you cross multiply, you have:
Mass of zinc= 5.8moles×65.38gmol-1
Mass of zinc= 379.204g
Therefore the mass of zinc present is 379.20 grams
